10-3 is equivalent to 0.001.
4-3 = 1/64
3-2 x 3-3 = 3-5 or 1/243
3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.
3^-1 = 1 over (3 to the power of 1) = 1/3, one third. a minus power is the same as a normal power but with a 1 above it.
10-3 is equivalent to 0.001.
3.27*10-3=.00327
10 - (3)3 = 10 - 9 = 1 (10 - 3)3 = (7)3 = 343
4-3 = 1/64
33 - 100 = 26
103 - 102 = 1,000 - 100 = 9 x 102 = 900

3/5 minus 3/10 is the same as 6/10 minus 3/10 = 3/10
minus 8..
6 to the power of 6 minus 3 to the power of 3 = 46,629
3-2 x 3-3 = 3-5 or 1/243
